JP 2000-42235 A (FIG. 1)

  In recent years, depending on the needs of the player, in addition to the normal form of sales with a ball rental fee of 4 yen / piece, a game with a ball rental fee of 1 yen / piece (commonly, “ The number of amusement halls that take the form of sales in “) is gradually increasing. In game halls that take two types of business forms, normal games and Ichipachi games, measures are taken to vary the color of pachinko balls so that the value of pachinko balls that differ for each business form can be distinguished at a glance. Specifically, in pachinko islands for regular games where the ball rental fee is 4 yen / piece, a golden pachinko ball (hereinafter also referred to as a gold ball) is used, while the ball rental fee is 1 yen / piece. In the pachinko island stand for the game, the silver pachinko ball (hereinafter also referred to as a silver ball) is used. When two different types of pachinko balls are used, multiple pachinko machines installed on one pachinko island stand will inevitably have a business form due to the configuration in which one type of pachinko balls is circulated and used in units of islands. It is standardized to either a normal game or a crack game.

  By the way, if it is going to adopt an island exchange type ball transfer device on the assumption that the above-mentioned two different types of pachinko balls are used, it is necessary to prevent two different types of pachinko balls (gold balls and silver balls) from being mixed. The conventional island exchange type ball transfer device cannot be used as it is. For example, in the conventional island exchange type ball transfer device shown in FIG. 13A, among pachinko island platforms C1 to C7 provided in a plurality of rows, between pachinko island platforms C2 and C3 and between pachinko island platforms C6 and C7. The base tanks T1 and T2 are arranged respectively, so that the pachinko island platforms C2, C3, C6 and C7 are the main pachinko island platforms adjacent to the base tanks T1 and T2, respectively, while adjacent to the base tanks T1 and T2. Pachinko island platforms C1, C4, and C5 that are not used are subordinate pachinko island platforms. The main pachinko island stand C2 and the sub pachinko island stand C1 constitute one island block, and similarly, the main pachinko island stand C3 and the sub pachinko island stand C4 are the main pachinko island stand C6 and the sub pachinko island. The platform C5 constitutes one island platform block, and between the base tank T1 and one island platform block C2, C1, and between the base tank T1 and the other island platform blocks C3, C4. Between the base tank T2 and another island block C6, C5, between the adjacent island block C3, C4 and the slave pachinko island platform C4 and C5 of the island block C6, C5, The pachinko balls are transported and used between the pachinko island platforms C1 to C7 by providing the pawls for conveying the pachinko balls respectively. As described above, in the conventional island exchange type ball transfer device, the pachinko balls are transferred and used in all the pachinko islands C1 to C7, but this is a configuration that can be adopted because the pachinko balls of the same quality are used. .

  In the configuration shown in FIG. 13 (A), the pachinko islands C1 and C2 are pachinko islands for chip game use, in other words, pachinko islands using silver balls, while the pachinko islands C3 to C7 are used for normal games. If the above-mentioned conventional island exchange type ball transfer device is used as it is as a pachinko island platform that uses gold balls as a pachinko island platform, the silver balls used in the pachinko island platforms C1 and C2 that constitute one island platform block. There are cases where the balls returned to the base tank T1 and the balls used in the other pachinko islands C3 and C4 constituting the other island block are returned to the base tank T1. Gold balls and silver balls are mixed together. Also, as for the base tank T2, the silver balls mixed in the base tank T1 are supplied to the pachinko island stand C3 side, and then returned to the base tank T2 through the pachinko island stands C4 to C6. , Gold balls and silver balls will be mixed.

  Therefore, as shown in FIG. 13 (B), the pachinko island stand C2 serving as the main pachinko island stand for the first game (silver ball corner) and the pachinko island stand serving as the main pachinko island stand for the normal game (gold ball corner). A base tank K dedicated to storage of gold balls and a base tank G dedicated to storage of silver balls are separately provided between C3 and the base tank T2 provided between the pachinko islands C6 and C7 is used exclusively for storage of gold balls. Thus, it is possible to avoid a mixture of gold balls and silver balls in each of the base tanks K, G, T2. In this case, the silver balls used in the pachinko islands C1 and C2 are always returned to the base tank G dedicated to storing silver balls, and from the base tank G dedicated to storing silver balls, the main pachinko islands C2 in the silver ball corner On the other hand, the ball used in the pachinko islands C3 and C4 is always returned to the base tank K dedicated to storing the ball, and from the base tank K dedicated to storing the ball, the main pachinko in the corner Supply only to the island stand C3.

  However, in the configuration shown in FIG. 13B as described above, it is necessary to make a large-scale modification to the conventional (existing) island AC ball transfer device shown in FIG. This causes a problem that it is applied. As specific modifications, it is necessary to install two base tanks K and G having new ball transport paths instead of the base tank T1. Since the existing base tank T1 supplies pachinko balls to the adjacent main pachinko island platforms C2 and C3, the bottom portion is provided with a collar portion that conveys the pachinko balls toward the pachinko island platforms C2 and C3. However, the base tanks K and G to be newly installed need to be provided with a flange for transporting pachinko balls only on one of the adjacent main pachinko island platforms C2 and C3. Must be changed.

  Therefore, by providing a partition plate inside the existing base tank T1, the ball storage space of the base tank T1 is used as a ball storage space (hereinafter referred to as a ball storage space) and a silver ball storage space (hereinafter referred to as a ball storage space). A configuration may be considered in which this is divided into a silver ball storage space) and stored so that two different types of pachinko balls are not mixed. However, when it is set as such a structure, when many difference arises in the amount of storage between the gold ball stored in the ball storage space and the silver ball stored in the silver ball storage space, between each storage space An enormous pressure difference is generated, and the partition plate is damaged by the pressure difference.

  The present invention has been made in view of the above circumstances, and the purpose thereof is to provide a partition plate inside the base tank, so that two types of pachinko balls are stored individually without mixing them, An object of the present invention is to provide an island exchange type ball transfer device in a game arcade that can prevent a partition plate from being damaged by a pressure difference between pachinko balls.

  In order to achieve the above-described object, in the invention of claim 1, between the main pachinko island platform for exchanging pachinko balls with the base tank storing a large amount of pachinko balls, and the main pachinko island platform A plurality of island block blocks, each including a slave pachinko island platform that exchanges pachinko balls, sandwiching the base tank, and the base tank and the main pachinko in each island block of the plurality of island block blocks In an amusement arcade provided with an island-interchange ball transfer device for exchanging pachinko balls between the island stand and the sub pachinko island stand, the playground includes a first pachinko ball in the ball storage space. The first island exchange for exchanging pachinko balls between the first base tank that stores the second pachinko balls different from the first pachinko balls so as not to be mixed individually and the plurality of island block 2nd island exchange type ball which exchanges pachinko balls between the 2nd base tank which stores the 2nd pachinko ball exclusively in the ball storage space, and a plurality of island stand blocks A transfer device, and the first base tank includes a first main pachinko island base constituting a first island base block of the plurality of island base blocks and a second island base block constituting a second island base block. The first pachinko ball used in the first island block is disposed in the ball storage space of the first base tank. And a second ball storage space for storing the second pachinko balls used in the second island block, and a partition plate is provided. One main pachinko island stand from the first ball storage space A first lower tank that receives the first pachinko ball via one inflow trough, and a first pachinko ball that has been fed from the first lower tank by a first ball lifting device in the island. A first upper tank to be stored, a first supply bowl for supplying the first pachinko balls stored in the first upper tank to a pachinko machine installed in the island, and the first upper tank The first pachinko ball that supplies the stored first pachinko ball to the first sub-pachinko island base that constitutes the first island block, and the first pachinko ball that overflows in the first upper tank A first return rod that returns to the first ball storage space of the first base tank, and the second main pachinko island stand receives a second inflow rod from the second ball storage space. A second lower tank for receiving the second pachinko ball via the second lower tank, The second upper tank for storing the second pachinko ball lifted by the second ball lifting device in the own island from the tank and the second pachinko ball stored in the second upper tank in the own island A second replenishment rod for replenishing the pachinko machine installed in the second upper pachinko ball and the second pachinko ball stored in the second upper tank to the second slave pachinko island base constituting the second island block A second supply rod for supplying, and a second return rod for returning the second pachinko ball overflowing in the second upper tank to the second ball storage space of the first base tank. The first island exchange type ball transfer device detects a first ball storage amount detection that detects a storage amount of the first pachinko ball stored in the first ball storage space of the first base tank. Means and before being stored in the second ball storage space of the first base tank Detected by the second ball storage amount detection means for detecting the storage amount of the second pachinko ball, the storage amount detected by the first ball storage amount detection means, and the second ball storage amount detection means Compared with the storage amount, the ball amount comparison / determination means for determining whether or not there is a difference greater than or equal to a predetermined storage amount, and the second ball storage space including the second ball storage space of the first base tank The ball transfer path for exchanging the second pachinko ball between the island stand block and the second island AC ball transfer device including the second base tank, and the ball amount comparison and determination means When it is determined that there is a difference greater than or equal to a predetermined storage amount, the storage amount detected by the first ball storage amount detection means and the storage amount detected by the second ball storage amount detection means are substantially the same. So that the second pachinko ball is played by the ball transfer path And Ball transport control means for controlling the Ri, characterized in that it comprises a.

  In the invention of claim 2, the ball storage space is formed in a rectangular parallelepiped shape in the first base tank, and the bottom surface of the ball storage space is centered from both longitudinal ends of the base tank. The first inclined portion communicating with the first inflow ridge and the second ridge portion communicating with the second inflow ridge are formed in a concave shape on the bottom surface of the central inclination. The partition plate is disposed at a substantially center in the longitudinal direction of the first base tank so as to be orthogonal to the longitudinal direction of the base tank, so that the rectangular ball storage space and the first basket And the second collar part are divided into left and right parts into the first ball storage space that communicates with the first collar part and the second ball storage space that communicates with the second collar part. It is characterized by doing.

  In the first aspect of the invention, the first main pachinko island base constituting the first island block and the first main pachinko island base constituting the second island block are the first ones. By providing a partition plate in the ball storage space of the base tank, the ball storage space is divided into a first ball storage space for storing the first pachinko balls used in the first island block, and a second island stand It divides | segments into the 2nd ball storage space which stores the 2nd pachinko ball used by a block. The first pachinko balls stored in the first ball storage space are supplied to the first lower tank of the first main pachinko island platform via the first inflow trough, and the first It is supplied from the lower tank to the first slave pachinko island base constituting the first island block through the first supply rod. After that, the first pachinko ball overflowing from the first main pachinko island base or the first sub pachinko island base is transferred from the first upper tank to the first base tank through the first return rod. Returned to the ball storage space. Similarly, the second pachinko balls stored in the second ball storage space are supplied to the second lower tank of the second main pachinko island platform via the second inflow trough, and the second Is supplied from the lower tank to the second sub-pachinko island base constituting the second island block through the second supply rod. After that, the second pachinko ball overflowing from the second main pachinko island base or the second sub pachinko island base is passed through the second return rod from the second upper tank to the second of the first base tank. Returned to the ball storage space. As a result, there are two types of remodeling that can be done by simply remodeling the existing base tank (first base tank) without making any major remodeling to the existing island AC ball transfer device. It is possible to realize an island exchange type ball transfer device that circulates and uses individually without mixing pachinko balls at a low cost.

  Moreover, according to the structure of the invention which concerns on Claim 1, the storage amount of the 1st pachinko ball currently stored in the 1st ball storage space of the 1st base tank, and the 2nd of the 1st base tank The amount of the second pachinko balls stored in the ball storage space is compared. And when there is a difference more than a predetermined storage amount that may damage the partition plate when the pressure of the pachinko ball is applied to the partition plate, the storage amount of the first pachinko ball in the first ball storage space and The second island stand block including the second ball storage space of the first base tank and the second so that the storage amount of the second pachinko ball in the second ball storage space is substantially the same. The second pachinko ball is controlled to be exchanged with the second island exchange type ball transfer device including the base tank. Thereby, the pressure with which the first pachinko balls stored in the first ball storage space press the partition plate, and the pressure with which the second pachinko balls stored in the second ball storage space press the partition plate, Can be made substantially equal so that there is almost no pressure difference between the first and second ball storage spaces. Moreover, even if the pressure of the pachinko ball is applied to the partition plate, the predetermined storage amount is set to such an amount that the partition plate is not damaged. Therefore, the partition plate can be prevented from being damaged by the pressure of the pachinko balls stored in the first and second ball storage spaces.

  Further, in the invention of claim 2, the first base tank having the bottom surface inclined downward from both ends in the longitudinal direction toward the center and having a rectangular parallelepiped ball storage space, A partition plate is attached at substantially the center in the longitudinal direction of the base tank so as to be orthogonal to the longitudinal direction of the base tank. And the 1st and 2nd collar part formed in the concave shape in the center inclination bottom face of the 1st base tank divides into the 1st ball storage space and the 2nd ball storage space which are connected individually. Thereby, since it can divide into 2 without making the 1st and 2nd ball storage space into a long and narrow space, the ball flow of the 1st pachinko ball in the 1st ball storage space, and the 2nd ball storage space The pachinko balls can be circulated and used smoothly without hindering the flow of the second pachinko balls inside. In the case of a long and thin ball storage space, the width dimension of the inclined bottom surface that rolls the pachinko ball in the ball storage space to the first and second collars in the center is optimal for rolling the pachinko ball. Therefore, there is a possibility that the flow of pachinko balls on the inclined bottom surface will be hindered.

  The structure of the pachinko island platform in the island exchange format has been described above. Next, base tanks B1 and B2 that are important components in the island exchange format will be described with reference to FIGS. The base tank B2 is a base tank dedicated to storing gold balls, and the basic tank structure is substantially the same as the base tank B1 except for a partition plate 34 described later. Therefore, in the following description, the structure of the base tank B1 will be mainly described, and the same constituent members in the base tanks B1 and B2 will be described with the same reference numerals.

  As shown in FIG. 3, the base tank B1 is formed of a plywood or a metal plate in a rectangular parallelepiped shape whose upper surface is open, and its bottom plate is inclined downward toward the center. That is, the base tank B1 having a horizontal rectangular upper surface opening 30 has a pair of left and right bottom plates 31 and 32 inclined downward from both ends in the longitudinal direction toward the center, and a downstream end portion of the bottom plates 31 and 32. On the center inclined bottom surface, the flange portions 31a and 32a that are individually inclined downward from the center in the lateral width direction (direction perpendicular to the longitudinal direction) of the base tank B1 toward both ends are formed in a concave shape. One saddle portion 31a has an inflow trough 20b passed between the base tank B1 and the lower tank 13 (inlet 18) of the pachinko island platform A3 that uses a gold ball among the main pachinko island platforms that sandwich the base tank B1. Connected. On the other hand, the other flange 32a is an inflow passed between the lower tank 13 (inlet 18) of the pachinko island platform A2 that uses silver balls among the main pachinko island platforms that sandwich the base tank B1 and the base tank B1. The bag 20a is connected.

  By the way, as described above, the base tank B1 of the present embodiment includes a silver ball that is a pachinko ball necessary for the pachinko islands A1 and A2 constituting the first island block and a pachinko island that constitutes the second island block. It is configured to be able to store the ball that is the pachinko ball necessary for the bases A3 and A4, but such a silver ball and a gold ball are used for different pachinko islands (island block). It is necessary to store separately in the base tank B1 without being mixed. For this reason, in this embodiment, the 2nd island stand block (pachinko island stand A3, A4) and the 3rd island stand block (pachinko island) are provided in the ball storage space 33 of the base tank B1. Used in the stand A5, A6) and the fourth island stand block (pachinko island stand A7 ~) and used in the first island stand block (pachinko island stand A1, A2). The inside of the ball storage space 33 is divided into two parts, the silver ball storage space 33b for storing the silver balls to be processed. Specifically, as shown in FIG. 4, the partition plate 34 is formed to have a height dimension substantially the same as the height dimension of the ball storage space 33 in the central inclined bottom surface portion of the base tank B <b> 1, and the longitudinal direction of the base tank B <b> 1. The first and second substrates 35 are arranged in parallel with each other, and are individually bent from both side ends of the substrate 35 and extended to positions where they contact the inner side walls of the base tank B1 when mounted. Bent plate portions 36 and 37, and an inflow trough partition portion 38 that protrudes downward from the lower center of the substrate portion 35. The first and second bent plate portions 36 and 37 are formed in a state where the first and second bent plate portions 36 and 37 are bent at right angles to each other in opposite directions from the respective side ends of the substrate portion 35, and substantially have the lateral width dimension of the ball storage space 33. The half length dimension (extended dimension) and the height dimension substantially the same as the substrate part 35 are formed. Further, the inflow trough partitioning portion 38 is formed to have a length dimension (projecting dimension) substantially the same as the height dimension of the concave trough portions 31a and 32a.

  Thus, as shown in FIG. 5, the partition plate 34 has the inflow saddle partition portion 38 inserted in the boundary portion between the flange portions 31a and 32a that are individually inclined downward toward both ends in the width direction of the base tank B1. In this state, it is attached in the ball storage space 33 of the base tank B1, and in this state, the first bent plate portion 36 is placed on one side of the base tank B1 in the lateral direction on the bottom plate 31 that is a lateral position of the flange portion 32a. On the other hand, the second bent plate portion 37 contacts the inner side of the other side wall in the lateral width direction of the base tank B1 on the bottom plate 32 which is a lateral position of the flange portion 31a. Arranged. As a result, the partition plate 34 uses the bottom plate 31 as the space bottom surface and the ball storage space 33a in which the flange portion 31a communicates with the space, and the bottom plate 32 as the space bottom surface and communicates the flange portion 32a with the space. The ball storage space 33 is divided into two parts. The base tank B2 disposed between the pachinko island platforms A6 and A7 includes a second island platform block (pachinko island platforms A3 and A4), a third island platform block (pachinko island platforms A5 and A6), and It is a base tank which specially stores the gold balls used in the fourth island stand block (pachinko island stand A7). Therefore, since the ball storage space 33 of the base tank B2 does not need to be divided into the ball storage space 33a and the silver ball storage space 33b unlike the base tank B1, the partition plate 34 is not provided.

  Further, as shown in FIG. 6, the ball storage space 33a and the silver ball storage space 33b of the base tank B1 are respectively stored in the left and right storage spaces 33a and 33b on the inner wall portion closer to the center (closer to the partition plate 34). The ball amount sensors 53a to 53e and 54a to 54e for detecting the amount of balls to be detected are provided. Specifically, the ball amount sensors 53a to 53e (second ball storage amount detection means) for detecting the storage amount of the gold balls in the base tank B1 are provided on the inner wall portion of the gold ball storage space 33a in order from the lower position. The ball amount sensors 54a to 54e (first ball storage amount detection means) which are attached in a row so as to be different and detect the storage amount of the silver balls in the base tank B1 are similarly provided on the inner wall portion of the silver ball storage space 33b. It is attached in a row so that the height is different from the lower position. Similarly to the base tank B1, a ball amount sensor 55a for detecting the amount of gold balls stored in the ball storage space 33 of the base tank B2 is provided on the inner wall portion closer to the center of the ball storage space 33 of the base tank B2. To 55e (see FIGS. 11 and 12).

  Further, the ball amount sensors 53a to 53e provided in the ball storage space 33a of the base tank B1, the ball amount sensors 54a to 54e provided in the silver ball storage space 33b of the base tank B1, and the base tank B2. The obtained ball amount sensors 55a to 55e are set to have substantially the same height position in the base tanks B1 and B2, respectively, and the storage amount level is sequentially increased from the ball amount sensors 53a, 54a, and 55a at the lower positions. It detects as levels 1-5. Based on the detection signals of the ball amount sensors 53a to 53e, 54a to 54e, and 55a to 55e, the shutter device is configured so that the storage amounts of the gold ball storage space 33a and the silver ball storage space 33b of the base tank B1 are equal. 51 and 52 are controlled to be opened. The control is automatically controlled by a ball amount control board 50 (see FIG. 2: ball amount comparison / determination unit, ball transfer control unit) provided inside the main pachinko island platform A2.

  That is, on the ball amount control board 50, as shown in FIG. 8, detection signals from the ball amount sensors 53a to 53e, 54a to 54e provided in the base tank B1 related to the own island (in FIG. 8, The detection signals from the ball amount sensors 54a to 54e are described as silver ball tank ball amount signals, and the detection signals from the ball amount sensors 53a to 53e are described as first gold ball tank ball amount signals) and the base tank B2. Detection signals from the ball amount sensors 55a to 55e (in FIG. 8, the detection signals from the ball amount sensors 55a to 55e are described as second ball sensor ball amount signals). . Thereby, the ball amount control board 50 is provided at the upstream end of the ball transfer path 6 based on the input of each detection signal (silver ball tank ball signal, first and second gold ball tank ball signal). A shutter device 51 (described as LC in the direction of the second metal ball tank → first metal ball tank in FIG. 8) and a shutter device 52 provided at the upstream end of the ball transfer path 7 (in FIG. The opening / closing control of each shutter device 51, 52 is performed by outputting a drive signal to the tank → second gold ball tank direction LC), and each of the ball ball storage space 33a and the silver ball storage space 33b of the base tank B1 is controlled. Control is made so that the amount of storage becomes equal. The specific opening / closing control of the shutter devices 51 and 52 by the ball amount control board 50 will be described in detail later.

  Furthermore, ball receiving plates 43 and 44 are provided in the ball storage space 33a and the silver ball storage space 33b of the base tank B1, respectively. Each of the ball receiving plates 43 and 44 is formed in a long plate shape extending along the longitudinal direction of the base tank B1, and is individually inclined downward toward both ends in the longitudinal direction of the base tank B1 with the central portion as a vertex. It is formed in a mountain shape. The ball receiving plate 43 is fixed to the upper portion of the inner wall of the base tank B1 constituting the gold ball storage space 33a by fixing means such as nails and bolts, and the ball receiving plate 44 is the inner wall of the base tank B1 forming the silver ball storage space 33b. It is fixed to the upper part of the door with fixing means such as nails and bolts.

  In addition, in the upper surface opening 30 of the base tank B1, an introduction rod 45 that communicates with the upper tank 22 of the pachinko island platform A3 via the return rod 4 is provided at a portion of the ball receiving plate 43 that faces the apex portion of the mountain shape. A ball discharge port 45a is arranged, and a portion of the ball receiving plate 44 that faces the apex portion of the mountain shape communicates with the upper tank 22 of the pachinko island stand A2 through the return rod 4 and the guide rods 46 and 47. A ball outlet 48a of the introduction basket 48 is arranged.

  Next, the exchange of pachinko balls between the base tank B1 described above and the main pachinko islands (pachinko islands A2, A3) sandwiching the base tank B1 will be described with reference to FIG. The upper tank 22 provided on the main pachinko islands (pachinko islands A2 and A3) gives top priority to the supply of pachinko balls to each pachinko machine 10 on its own island, and exchanges are made when the supply is no longer necessary. It is configured to guide the pachinko balls to the slave pachinko islands (pachinko islands A1, A4) via the cages 3b, 3c, and to return the surplus pachinko balls to the base tank B1 when the guidance is no longer necessary. ing.

  First, the exchange of pachinko balls (silver balls) between the base pachinko island stand (main pachinko island stand A2) and the base tank B1 for a lapping game with a lending fee of 1 yen / piece will be described. When the silver balls are returned from the main pachinko island stand A2 to the base tank B1, as shown in FIG. 7B, the upper tank 22 of the main pachinko island stand A2 is placed on the base tank B1 via the return basket 4. A silver ball is fed into the guide rod 46 provided. The silver balls fed into the guide rod 46 are guided to the introduction rod 48 through the guide rod 47, and then, on the ball receiving plate 44 from the ball discharge port 48a of the introduction rod 48, as shown in FIG. To be discharged. As a result, the silver balls discharged onto the ball receiving plate 44 are reduced in falling speed by the ball receiving plate 44 and distributed to the left and right on the ball receiving plate 44 inclined in a mountain shape, thereby causing the base tank B1. Are sent into the silver ball storage space 33b. Further, the silver balls fed into the silver ball storage space 33b roll on the bottom plate 32 constituting the bottom surface of the silver ball storage space 33b as shown in FIG. To the center side (the side of the flange 32a with which the inflow rod 20a is communicated). And when sufficient silver balls are stored in the lower tank 13 of the main pachinko island platform A2, the lower tank 13 of the main pachinko island platform A2 from the silver ball storage space 33b of the base tank B1 through the inflow trough 20a. When the supply of the silver balls to is stopped, surplus silver balls are stored in the silver ball storage space 33b of the base tank B1. On the other hand, when the silver balls stored in the lower tank 13 of the main pachinko island stand A2 are insufficient, the silver balls stored in the silver ball storage space 33b of the base tank B1 are passed through the inflow trough 20a. It is supplied to the lower tank 13 of the main pachinko island stand A2.

  Next, the exchange of pachinko balls (gold balls) between the base pachinko island stand (pachinko island stand A3) and the base tank B1 for a normal game with a ball rental fee of 4 yen / piece will be described. When the ball is returned from the main pachinko island stand A3 to the base tank B1, as shown in FIG. 7B, the upper pachinko island stand A3 is provided on the base tank B1 via the return basket 4 from the upper tank 22. A ball is sent into the introduced introduction basket 45. As shown in FIG. 7E, the ball sent to the introduction basket 45 is discharged onto the ball receiving plate 43 from the ball discharge port 45 a of the introduction basket 45. As a result, the ball discharged on the ball receiving plate 43 is reduced in its falling speed by the ball receiving plate 43 and inclined in a mountain shape, like the silver ball discharged on the ball receiving plate 44. The balls are distributed left and right on the ball receiving plate 43 and fed into the ball storage space 33a of the base tank B1. Further, as shown in FIG. 7C, the gold balls fed into the gold ball storage space 33a roll on the bottom plate 31 that constitutes the bottom surface of the gold ball storage space 33a, and the center side in the longitudinal direction of the base tank B1. It is guided to the flange 31a side where the inflow rod 20b is communicated. And when sufficient gold balls are stored in the lower tank 13 of the main pachinko island platform A3, the ball storage space 33a of the base tank B1 via the inflow rod 20b leads to the lower tank 13 of the main pachinko island platform A3. By stopping supply of the gold balls, surplus gold balls are stored in the gold ball storage space 33a of the base tank B1. On the other hand, when there are not enough balls stored in the lower tank 13 of the main pachinko island stand A3, the balls stored in the ball storage space 33a of the base tank B1 are connected to the main pachinko island via the inflow rod 20b. The lower tank 13 of the table A3 is replenished.

  By the way, when storing the pachinko balls in the ball storage space 33a and the silver ball storage space 33b of the base tank B1, there is a large difference in the storage amount of the pachinko balls stored in the left and right storage spaces 33a and 33b. Is a large pressure difference caused by the pachinko balls between the left and right storage spaces 33a and 33b. And when such a big pressure difference arises, there exists a possibility that the partition plate 34 which divides the storage spaces 33a and 33b on either side may be damaged. Therefore, in the present embodiment, a shutter device 52 that adjusts the ball flow from the base tank B1 to the base tank B2 and a shutter device that adjusts the ball flow from the base tank B2 to the base tank B1. 51, and the shutter devices 51 and 52 are controlled to be opened and closed by the ball amount control board 50, thereby preventing the partition plate 34 from being damaged due to a large pressure difference. Hereinafter, opening / closing control of the shutter devices 51 and 52 by the ball amount control board 50 will be described with reference to FIGS.

  First, in the ball amount control process shown in FIG. 9, the ball amount control board 50 is a ball that is stored in a ball storage space 33a of the base tank B1 (denoted as the first metal ball tank in FIGS. 9 and 10). After receiving detection signals from the ball amount sensors 53a to 53e (step S1), the silver ball storage space 33b of the base tank B1 (in FIG. 9 and FIG. In order to grasp the storage amount level of the silver balls stored in the ball), detection signals from the ball amount sensors 54a to 54e are input (step S2), and then the ball storage space 33 (see FIG. 9) of the base tank B2. And in FIG. 10, in order to grasp | ascertain the storage amount level of the gold | metal | money stored in the 2nd metal ball tank), the detection signal from the ball quantity sensors 55a-55e is input (step S3). Thereafter, it is determined whether or not the storage amount level of the gold balls in the ball storage space 33a input in step S1 and the storage amount level of the silver balls in the silver ball storage space 33b input in step S2 are the same (step). S4). When the storage amount level of the gold balls in the ball storage space 33a and the storage amount level of the silver balls in the silver ball storage space 33b are the same in step S4, the ball amount control process is finished as it is.

  On the other hand, when the storage amount level of the gold balls in the ball storage space 33a and the storage amount level of the silver balls in the silver ball storage space 33b are not the same in step S3, as shown in FIG. 10, the ball input in step S1. Whether the storage amount level of the gold balls in the storage space 33a is smaller than the storage amount level of the silver balls in the silver ball storage space 33b input in step S2, in other words, the storage amount of the gold balls in the base tank B1 is It is determined whether or not the amount is less than the stored amount (step S5). When the stored amount of the gold balls in the base tank B1 is smaller than the stored amount of the silver balls in step S5, it is determined whether or not the stored amount level of the gold balls in the base tank B2 input in step S3 is level 4 or higher. (Step S6). When the storage amount level of the gold balls in the base tank B2 is smaller than the level 4 in step S6, a sufficient amount of gold balls that can be supplied to the gold ball storage space 33a of the base tank B1 is not stored in the base tank B2. In order to stop the transfer of the gold balls from the base tank B2 side to the base tank B1 side and the transfer of the gold balls from the base tank B1 side to the base tank B2 side, both shutter devices 51, 52 (in FIG. 10) Is closed (step S7a), and a signal to the effect that the difference in the amount of balls between the left and right storage spaces 33a and 33b cannot be filled is output to the hall computer (step S7b). ), The ball amount control process is terminated.

  Further, when the storage amount level of the gold balls in the base tank B2 is equal to or higher than level 4 in step S6, a sufficient amount of gold balls are stored in the base tank B2 to supply the gold balls storage space 33a of the base tank B1. The shutter device 52 (denoted as LC in FIG. 10) provided at the upstream end of the ball transfer path 7 is closed to stop the transfer of the gold balls from the base tank B1 side to the base tank B2 side. In addition to the control (step S8a), the shutter device 51 (denoted as LC in FIG. 10) provided at the upstream end of the ball transfer path 6 is controlled to open so as to transfer the gold ball from the base tank B2 side to the base tank B1 side. (Step S8b). Thereafter, it is determined whether or not the storage amount level of the gold balls in the gold ball storage space 33a is the same as the storage amount level of the silver balls in the silver ball storage space 33b (step S9). When the storage amount level of the gold balls in the ball storage space 33a and the storage amount level of the silver balls in the silver ball storage space 33b are not the same in step S9, the storage amounts of the ball storage space 33a and the silver ball storage space 33b are as follows. It is determined that there is a pressure difference between the left and right storage spaces 33a and 33b, and the process proceeds to step S5 again. Moreover, when the storage amount level of the gold balls in the ball storage space 33a and the storage amount level of the silver balls in the silver ball storage space 33b are the same in step S9, each storage of the gold ball storage space 33a and the silver ball storage space 33b is performed. It is determined that there is no difference in pressure between the right and left storage spaces 33a and 33b, the ball is transferred from the base tank B2 side to the base tank B1 side, and the base tank B2 side is moved to the base tank B2. Both shutter devices 51 and 52 are controlled to be closed in order to stop the transfer of the gold balls to the side (step S10), and the ball amount control process is terminated.

  On the other hand, when the storage amount of the gold balls in the base tank B1 is larger than the storage amount of the silver balls in step S5, whether or not the storage amount level of the gold balls in the base tank B2 input in step S3 is less than level 2. Is discriminated (step S11). When the storage amount level of the gold balls in the base tank B2 is level 2 or more in step S11, it is determined that there is not enough free space in the base tank B2 to store the gold balls transferred from the gold ball storage space 33a of the base tank B1. Thus, both shutter devices 51, 52 (all in FIG. 10 are all shown in order to stop the transfer of the gold balls from the base tank B2 side to the base tank B1 side and the transfer of the gold balls from the base tank B1 side to the base tank B2 side. LC (described as LC) is controlled to be closed (step S12a), and a signal indicating that the difference in the amount of balls between the left and right storage spaces 33a and 33b cannot be filled is output to the hall computer (step S12b). The amount control process ends. Further, when the storage amount level of the gold balls in the base tank B2 is less than level 2 in step S11, the base tank B2 has enough free space to store the gold balls transferred from the gold ball storage space 33a of the base tank B1. The shutter device 51 (denoted as LC in FIG. 10) provided at the upstream end of the ball transfer path 6 is controlled to be closed so as to transfer the gold ball from the base tank B2 side to the base tank B1 side (step). S13a), the shutter device 52 (referred to as LC in FIG. 10) provided at the upstream end of the ball transfer path 7 is controlled to open to transfer the gold balls from the base tank B1 side to the base tank B2 side (step S13b). . Thereafter, the process proceeds to step 9, and it is determined whether or not the storage amount level of the gold balls in the ball storage space 33a and the storage amount level of the silver balls in the silver ball storage space 33b are the same. When the storage amount level of the gold balls in the ball storage space 33a and the storage amount level of the silver balls in the silver ball storage space 33b are not the same in step S9, the storage amounts of the ball storage space 33a and the silver ball storage space 33b are as follows. It is determined that there is a pressure difference between the left and right storage spaces 33a and 33b, and the process proceeds to step S5 again. On the other hand, when the storage amount level of the gold balls in the ball storage space 33a and the storage amount level of the silver balls in the silver ball storage space 33b are the same in step S9, each storage in the gold ball storage space 33a and the silver ball storage space 33b. It is determined that there is no difference in pressure between the right and left storage spaces 33a and 33b, the ball is transferred from the base tank B2 side to the base tank B1 side, and the base tank B2 side is moved to the base tank B2. In order to stop the transfer of the gold balls to the side, both shutter devices 51 and 52 (described as all LCs in FIG. 10) are closed (step S10), and the ball amount control process is terminated.

  Next, an example of specific opening / closing control of the shutter devices 51 and 52 will be described with reference to FIGS. 11 and 12. First, in the opening / closing control of the shutter device 52 for transferring a gold ball from the base tank B1 side to the base tank B2 side, as shown in FIG. 11A, five ball amounts provided in the gold ball storage space 33a of the base tank B1. While the ball amount sensors 53a to 53c from the bottom to the third of the sensors 53a to 53e detect the gold balls, the storage amount level of the gold balls in the gold ball storage space 33a is detected as level 3, while the base tank B1 The ball amount sensors 54a to 54c of the five ball amount sensors 54a to 54e provided in the silver ball storage space 33b from the bottom detect the silver balls, so that the silver in the silver ball storage space 33b is detected. If the storage amount level of the balls is detected as level 3 which is the same as the storage amount level of the gold balls in the ball storage space 33a, based on this, the ball storage space 33a and the silver ball storage space 33 are detected. Each storage amount is equal left and right of the storage space 33a of, it is determined that no cause pressure difference between 33b. The shutter device 52 is closed (OFF) because there is no need to transfer the gold ball from the base tank B1 side to the base tank B2 side. At this time, the shutter device 51 is similarly controlled to be closed (OFF) because it is not necessary to transfer the gold ball from the base tank B2 side to the base tank B1 side.

  Moreover, as shown in FIG. 11 (B), the ball amount sensors 53a to 53c from the bottom to the third of the five ball amount sensors 53a to 53e provided in the gold ball storage space 33a of the base tank B1 are used as the balls. By detecting, the level of stored amount of gold balls in the gold ball storage space 33a is detected as level 3, while from the bottom of the five ball amount sensors 54a to 54e provided in the silver ball storage space 33b of the base tank B1. Level 2 in which the storage amount level of the silver balls in the silver ball storage space 33b is lower than the storage amount level of the gold balls in the gold ball storage space 33a because the second ball amount sensors 54a and 54b detect the silver balls. Based on this, it is determined that the balance between the storage amounts of the gold ball storage space 33a and the silver ball storage space 33b is lost and a pressure difference is generated between the left and right storage spaces 33a and 33b. Then, only the first ball amount sensor 55a from the bottom among the five ball amount sensors 55a to 55e provided in the ball storage space 33 of the base tank B2 detects the gold ball, thereby storing the amount of the gold ball in the base tank B2. When the level is detected as level 1, based on this, it is determined that there is enough free space in the base tank B2 to store the gold balls transferred from the gold ball storage space 33a of the base tank B1, and from the base tank B1 side. The shutter device 52 is controlled to be opened (ON) so as to transfer the ball to the base tank B2 side. At this time, the shutter device 51 is closed (OFF) because there is no need to transfer the gold ball from the base tank B2 side to the base tank B1 side. The shutter device 52 is controlled to be closed (OFF) when the storage amounts of the gold ball storage space 33a and the silver ball storage space 33b become equal and no pressure difference is generated between the left and right storage spaces 33a and 33b. The transfer of the gold balls from the base tank B1 side to the base tank B2 side is stopped.

  However, as shown in FIG. 11 (C), the storage amount level of the gold balls in the ball storage space 33a is detected as level 3, while the storage amount level of the silver balls in the silver ball storage space 33b is detected as the gold ball storage space 33a. Even when it is detected as level 2 lower than the stored amount level of the gold balls inside and it is determined that there is a pressure difference between the left and right storage spaces 33a, 33b, it is provided in the ball storage space 33 of the base tank B2. When all the five ball quantity sensors 55a to 55e detect the gold balls and the level of the gold balls stored in the base tank B2 is detected as level 5, the balls transferred from the gold ball storage space 33a of the base tank B1 are stored. It is determined that there is not enough free space in the base tank B2. As a result, the shutter device 52 is closed (OFF), and the ball is not transferred from the base tank B1 side to the base tank B2 side.

  Next, in the opening / closing control of the shutter device 51 that transfers the gold ball from the base tank B2 side to the base tank B1 side, as shown in FIG. 12A, five balls provided in the gold ball storage space 33a of the base tank B1. While the ball amount sensors 53a to 53c from the bottom three of the amount sensors 53a to 53e detect the gold balls, the storage amount level of the gold balls in the gold ball storage space 33a is detected as level 3, while the base tank Of the five ball amount sensors 54a to 54e provided in the silver ball storage space 33b of B1, the ball amount sensors 54a to 54c from the bottom to the third ball amount sensor 54a to 54c detect the silver balls, whereby the inside of the silver ball storage space 33b. When the storage amount level of silver balls is detected as level 3 which is the same as the storage amount level of gold balls in the ball storage space 33a, based on this, the ball storage space 33a and the silver ball storage space 33 are detected. Each storage amount is equal left and right of the storage space 33a of, it is determined that no cause pressure difference between 33b. The shutter device 51 is controlled to be closed (OFF) because there is no need to transfer the gold ball from the base tank B2 side to the base tank B1 side. At this time, the shutter device 52 is also controlled to be closed (OFF) since it is not necessary to transfer the gold ball from the base tank B1 side to the base tank B2 side.

  Moreover, as shown in FIG. 12 (B), the ball amount sensors 53a and 53b from the bottom to the second of the five ball amount sensors 53a to 53e provided in the gold ball storage space 33a of the base tank B1 are used as the balls. By detecting, the level of stored amount of gold balls in the gold ball storage space 33a is detected as level 2, while the five ball amount sensors 54a to 54e provided in the silver ball storage space 33b of the base tank B1 are viewed from below. Level 3 in which the storage amount level of the silver balls in the silver ball storage space 33b is higher than the storage amount level of the gold balls in the ball storage space 33a by detecting up to the third ball amount sensors 54a to 54c. Based on this, it is determined that the balance between the storage amounts of the gold ball storage space 33a and the silver ball storage space 33b is lost and a pressure difference is generated between the left and right storage spaces 33a and 33b. And the ball amount sensor 55a-55d from the bottom to the 4th ball amount sensor 55a-55e provided in the ball storage space 33 of the base tank B2 detects the gold ball, and thereby the inside of the base tank B2 When the stored amount level of the gold balls is detected as level 4, based on this, it is determined that a sufficient amount of gold balls are stored in the base tank B2 to supply the gold balls storage space 33a of the base tank B1. The shutter device 51 is controlled to be opened (ON) so as to transfer the gold ball from the base tank B2 side to the base tank B1 side. At this time, the shutter device 52 is closed (OFF) because there is no need to transfer the gold ball from the base tank B1 side to the base tank B2 side. The shutter device 51 is controlled to be closed (OFF) when the storage amounts of the gold ball storage space 33a and the silver ball storage space 33b become equal and no pressure difference is generated between the left and right storage spaces 33a, 33b. The transfer of the gold balls from the base tank B2 side to the base tank B1 side is stopped.

  However, as shown in FIG. 12 (C), the storage amount level of the gold balls in the ball storage space 33a is detected as level 2, while the storage amount level of the silver balls in the silver ball storage space 33b is detected as the gold ball storage space 33a. Even when it is detected as level 3 higher than the stored amount level of the gold balls inside and it is determined that there is a pressure difference between the left and right storage spaces 33a, 33b, it is provided in the ball storage space 33 of the base tank B2. When only the first ball amount sensor 55a from the bottom among the five ball amount sensors 55a to 55e detects the gold ball and the level of the gold ball stored in the base tank B2 is detected as level 1, the gold ball in the base tank B1 It is determined that a sufficient amount of gold balls that can replenish the storage space 33a is not stored in the base tank B2. As a result, the shutter device 51 is controlled to be closed (OFF), and the ball is not transferred from the base tank B2 side to the base tank B1 side.

  As described above, according to the configuration of the present embodiment, the main pachinko island stand A2 (first main pachinko island stand) constituting the first island stand block and the main pachinko island stand constituting the second island stand block. By providing the partition plate 34 in the ball storage space 33 of the base tank B1 (first base tank) arranged between A3 (second main pachinko islands), the ball storage space 33 is Silver ball storage space 33b (first ball storage space) for storing silver balls (first pachinko balls) used in one island stand block and gold ball (second pachinko balls) used in second island stand block The ball is divided into a ball storage space 33a (second ball storage space) for storing the ball). The silver balls stored in the silver ball storage space 33b are supplied to the lower tank 13 (first lower tank) of the main pachinko island stand A2 via the inflow rod 20a (first inflow rod). It is supplied from the lower tank 13 to the slave pachinko island platform A1 (first slave pachinko island platform) constituting the first island platform block via the alternating current cage 3b (first supply cage). Thereafter, the silver balls overflowing from the main pachinko island stand A2 or the sub pachinko island stand A1 are returned from the upper tank 22 (first upper tank) of the main pachinko island stand A2 via the return basket 4 (first return basket). It is returned to the silver ball storage space 33b of the base tank B1. Similarly, the gold balls stored in the gold ball storage space 33a are supplied to the lower tank 13 (second lower tank) of the main pachinko island base A3 via the inflow rod 20b (second inflow rod), and the It is supplied from the lower tank 13 to the secondary pachinko island platform A4 (second secondary pachinko island platform) that constitutes the second island platform block through the alternating current cage 3c (second supply cage). After that, the ball overflowing from the main pachinko island stand A3 or the sub pachinko island stand A4 is returned to the base from the upper tank 22 (second upper tank) of the main pachinko island stand A3 via the return basket 4 (second return basket). It is returned to the ball storage space 33a of the tank B1. As a result, two types of pachinko balls (a ball and a ball) can be obtained by simply modifying the existing base tank B1 without providing a major modification to the existing island AC ball transfer device. It is possible to realize an island exchange type ball transfer device that circulates and uses them individually without mixing them at low cost.

  Moreover, according to the structure of this embodiment, the storage amount of the gold balls stored in the gold ball storage space 33a of the base tank B1, and the storage of the silver balls stored in the silver ball storage space 33b of the base tank B1. Compare the amount. When the pressure of the pachinko ball is applied to the partition plate 34, when there is a difference greater than a predetermined storage amount that may cause the partition plate 34 to be damaged, the storage amount of the gold ball in the gold ball storage space 33a and the storage of the silver ball Control is performed to exchange the ball between the ball storage space 33a side of the base tank B1 and the base tank B2 side (second base tank) so that the amount of silver balls stored in the space 33b is substantially the same. . As a result, the pressure at which the gold balls stored in the gold ball storage space 33a press the partition plate 34 and the pressure at which the silver balls stored in the silver ball storage space 33b press the partition plate 34 are substantially equal to each other. Almost no pressure difference can occur between the storage spaces 33a and 33b. Moreover, even if the pressure of the pachinko ball is applied to the partition plate 34, the predetermined storage amount is set to such an amount that the partition plate 34 is not damaged. Therefore, it is possible to avoid the partition plate 34 from being damaged by the pressure of the pachinko balls stored in the gold ball storage space 33a and the silver ball storage space 33b.

  Further, the base tank B1 having the bottom surfaces 31 and 32 inclined downward from both ends in the longitudinal direction and having a rectangular parallelepiped ball storage space 33 formed therein is substantially at the center in the longitudinal direction of the base tank B1. A silver ball storage space in which the flange 32a (first flange) and the flange 31a (second flange) formed on the central inclined bottom surface of the base tank B1 communicate with each other by attaching the partition plate 34 to the wall. It is divided into left and right parts 33b and a ball storage space 33a. Thereby, since it can divide into 2 without making the ball storage space 33a and the silver ball storage space 33b into a long and thin space, the flow of silver balls in the silver ball storage space 33b and the movement of the gold balls in the ball storage space 33a Pachinko balls can be circulated smoothly without hindering the flow of balls. In addition, when it is set as the long and thin ball storage space, the width dimension of the inclined bottom surfaces 31 and 32 which roll the pachinko ball in the ball storage space 33 to the center collar part 31a and 32a rolls a pachinko ball. There is a possibility that the ball flow of the pachinko balls on the bottom surfaces 31 and 32 may be hindered due to the fact that it is greatly reduced from the value optimally designed above.

  In the above-described embodiment, the pachinko islands A1 to A6 and A7 are arranged in a row, and the base tank B1 capable of storing two types of pachinko balls (gold and silver balls) between the main pachinko islands A2 and A3 is provided. Although one is provided and one base tank B2 dedicated to one type of pachinko ball (gold ball) is provided between each of the pachinko islands A6 and A7, the number of pachinko islands and base tanks arranged in a row is shown. Is not limited to the configuration in the embodiment. However, when the types of pachinko balls used on the left and right main pachinko islands sandwiching the base tank are the same, it is not necessary to provide the partition plate according to the present invention in the base tank (the ball storage space is the first). If the types of pachinko balls used on the left and right main pachinko islands sandwiching the base tank are different from each other, the base tank is separated by the partition plate according to the present invention. It is necessary to divide the ball storage space into two first and second ball storage spaces.

  Further, in this embodiment, the ball amount sensor is disposed as the ball storage amount detection means so that the storage amount of the pachinko balls can be detected step by step, but the ball storage amount detection means can be any one that can detect the storage amount. Any configuration may be used. For example, a plurality of ball quantity sensors may be provided in the ball storage space, and the storage quantity may be detected by the ratio between the total number of ball quantity sensors and the number of ball quantity sensors that have detected pachinko balls.

  Moreover, in this embodiment, although the storage amount level is set corresponding to the detection result of the ball amount sensor, what is necessary is just to be able to set the storage amount level based on the detection result of the ball amount sensor. For example, if five ball quantity sensors are provided step by step, when the first or second pachinko ball is detected from the bottom, the amount of pachinko balls is set as the storage amount level 1, and the third from the bottom detects the pachinko ball. The storage amount level 2 may be set, and when the pachinko balls are detected by the fourth or fifth from the bottom, the storage amount level 3 may be set.

  Further, in this embodiment, the state where the storage amount level is different is used as the ball transfer control start condition. However, the present invention is not limited to this, and the difference between the storage amount levels in a plurality of stages is used as the ball transfer control start condition. Also good.
